Android - Fetching Array with no name

Question

I understand that what I'm fetching is already an array but still I'm not sure what to change here.

I have this which is returning data fine but I'm not sure what to do with the array to get the values into the map.

protected Void doInBackground(Void... params) {
        // Create an array
        arraylist = new ArrayList<HashMap<String, String>>();
        // Retrieve JSON Objects from the given URL address
        jsonobject = JSONfunctions
                .getJSONfromURL("http://www.mywebsite.club/api/coffees");

        try {
            // Locate the array name in JSON
            jsonarray = jsonobject.getJSONArray("coffees");

            for (int i = 0; i < jsonarray.length(); i++) {
                HashMap<String, String> map = new HashMap<String, String>();
                jsonobject = jsonarray.getJSONObject(i);
                // Retrive JSON Objects
                map.put("title", jsonobject.getString("title"));
                map.put("brand", jsonobject.getString("brand"));
                map.put("price", jsonobject.getInt("price"));
                map.put("brandlogo", jsonobject.getString("brandlogo"));
                // Set the JSON Objects into the array
                arraylist.add(map);
            }
        } catch (JSONException e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return null;
    }

You can just append json array in response from the url. "{coffees:" + url_reponse + "}" after that u can go ahead and get jsonarray as coffees — Vijay

From your response, I didn't find coffees attribute as array name, in your json response you have only array without attribute name. So you don't need to get json object from response, whatever your response string just get json array from that like, JSONArray jsonarray = new JSONArray(jsonobject.toString()); — user370305

    try {
         if(jsonarray != null)
         {

          for (int i = 0; i < jsonarray.length(); i++) {
            HashMap<String, String> map = new HashMap<String, String>();
            jsonobject = jsonarray.getJSONObject(i);
            // Retrive JSON Objects
            map.put("title", jsonobject.getString("title"));
            map.put("brand", jsonobject.getString("brand"));
            map.put("price", jsonobject.getInt("price"));
            map.put("brandlogo", jsonobject.getString("brandlogo"));
            // Set the JSON Objects into the array
            arraylist.add(map);
          }
       }
    } catch (JSONException e) {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
    }
    return null;
